Retractable Stainless Steel Bollard - 4" x 36" Manual Drop-Down

Heavy-Duty Manual Drop-Down Security Post with Reflective Strip

Block traffic when you need to. Let it through when you don't. This 4" retractable bollard drops flat into an in-ground sleeve for vehicle access, then locks upright for full perimeter security. SS316 marine-grade stainless steel handles coastal salt air, pressure washing, and wet conditions without rusting or staining.

Standing 36 inches above grade when locked, the bollard retracts fully into its 42" deep in-ground sleeve when access is needed. The integrated reflective strip keeps it visible after dark. Polished stainless finish stays clean without painting or maintenance.
